Hi,

i want to stream audio (from file and live) from FreeSwitch to multiple SIP endpoints (these are proprietary).
Because of bandwith limitations we have to use IP multicast for audio data.

Now the question: how can i do this smartly in FreeSwitch?

I have read some Wiki entries:
- mod_esf: seams to use multicast, but i couldn't find usage information
- mod_shout: streaming, but from internet ? MP3, but i want wav-files to stream
- mod_local_stream: seams to play files in a loop, i want to play a whole file once.
- mod_conference: seams not to support IP multicast

Im searching for a simple way to send a SIP INVITE to all my endpoints and
then stream audio (live from soundcard or from file) over IP multicast to all these endpoints.

Thanks in advance,
Thomas

ok, if no one has an idea 2 more specific questions:
1. is there any example for usage of mod_esf out there?
2. is it possible to use ip multicast for audio RTP in mod_conference (only 1 direction: single point to multi point)?

Thanks in advance,
Thomas
